Description
Using the ntp-service broadcast-client command, you can configure the NTP
broadcast client mode. Using the undo ntp-service broadcast-client command, you
can remove the NTP broadcast client mode.
By default, no NTP broadcast client service is configured.
This command is used to specify the local interface on the local device to receive
the NTP broadcast packets. The local device is run in client mode. It first listens
discreetly to the broadcast packets from the server. When the first broadcast
packet is received, the local device enables a short client/server mode to exchange
messages with the remote server in order to estimate network delay. Then it enters
the client mode to listen discreetly to the broadcast packets and synchronize the
local clock according to the coming broadcast packets.
Example
Enable the interface Ethernet 1/0/1 to receive NTP broadcast message.
[3Com] interface ethernet 1/0/1
